Most people on FB have no real life friends either. That's why they're so keen to accumulate "friends" on FB.
This reminds me of this speech by Erich Schmidt, former Google CEO:
"Take your eyes off that screen and look into the eyes of the person that you love. Have a conversation--a real conversation with the friends who make you think, with the family who make you laugh. Don't push a button saying I like something, actually tell them! What a concept!
Engage in the world around you and feel, taste, and smell and hug what's right there right in front of you, not what's a click away. Life is not lived in the glow of monitor. Life is not a series of status updates.
Life is not about your friend count, it's the friends who you can actually count on. Right? So life is about who you love, how you live, it's about who you travel with through the world. Your family, your collaborators, your friends. Life is a social experience first, and the best aspects of that experience are not lonely ones, they're spent in the company of others. Our modern landscape has changed yes-- but our humanity will always remain, and that, above all else, is what makes us who we are."
